jbd2: clean __jbd2_journal_abort_hard() and __journal_abort_soft() (2020-01-25 03:01:56 -0500)

This merge window, we've added some performance improvements in how we
handle inode locking in the read/write paths, and improving the
performance of Direct I/O overwrites. We also now record the error
code which caused the first and most recent ext4_error() report in the
superblock, to make it easier to root cause problems in production
systems. There are also many of the usual cleanups and miscellaneous
bug fixes.
